Abstract
Coherent optical data processing (CODP)1 offers many potential advantages in image processing as well as in the processing of wide bandwidth electrical signals. This technology has heretofore been limited by the need for a fast high-resolution realtime spatial light modulator (SLM).2,3 These devices function to impose on a coherent optical beam a 2-D image that is derived from either an incoherent optical source (photoactivated SLM) or directly from a properly formatted electrical input signal. The first of these tasks can be accomplished with the photoactivated HYFEM liquid crystal light valve (LCLV)4,5 described previously. This type of device operates in conjunction with an optical input source such as a CRT or a laser scanner to provide a real-time coherent output image.
